Indeed, this is even better as there won't be any unused objects included
in output this way. Good idea!

You need to keep the `*(.alphalib)' line only, i.e. drop the first and
the last line added by the patch, as the output section statement and its
curly braces surrounding input section specifiers are already produced
elsewhere. As a good measure you may want to prepend `ALIGN_FUNCTION();'
as well, although I'm not sure offhand if it really matters here.
